Sophie has factored the term completely while Carlos has not factored the term completely.
Step-by-step explanation:
We need to factor the trinomial:

Factoring:

So, the factored form of
is 
So, Sophie has factored the term completely. The terms are factored when we cannot further simplify it. Since Carlos factored (x+3)(-4x+2) 2 can be taken common from the term (-4x+2) so, it is not factored completely.

Answer:
Step-by-step explanation:
cost is 20 fee + .25 per mile.
c =20+0.25m
By graphing the polynomial, we conclude that there is only one real root, so the correct option is A.
<h3>
How many roots has the given polynomial?</h3>
We have the polynomial:

To see how many real roots this polynomial has, we can graph it and see how many times the graph intercepts the x-axis.
The graph can be seen below:
There we can see that there is only one intercept, so there is only one real root.
So the correct option is A.

Answer:
Step-by-step explanation:
4x+8=6x-1
<u>-4x . =-4x .</u>
8 = 2x-1
<u>-1+8=2x-1+1 </u>
7=2x
7/2= 2x/2
